Fun blog, but I think you may be missing "the point." Quotation marks are the less sophisticated way to "emphasize" something, perhaps to make it seem as if someone's voice is "speaking" with gusto the parts that are being quoted. They are not being used with any awareness of the more sardonic tendency to put something in quotation marks in order to disown responsibility for its veracity, or to make it seem contingent or "so-called." The rampant apostrophe on the other hand, now "that's" a true goofball mistake. -kc
